PiHole server stops responding and starts again

Help

I’m not sure if this is strictly a PiHole issue, but I think you guys and gals might be able to help.

I’m running PiHole on an Odroid Single Board Computer.

Welcome to Ubuntu 16.04.4 LTS (GNU/Linux 3.14.79-117 aarch64)

I’ve started having problems where I can’t browse the internet. I noticed I could ping google DNS 8.8.4.4 but pinging DNS names didn’t work. My router points to my PiHole server for all DNS resolutions. So then I noticed I couldn’t ping my PiHole server, much less remote in via SCP. After a few minutes, without having changed a single setting anywhere in my network, everything starts working again.

Is there a log file somewhere that I can examine the time period where things stopped and started working again that might give me a clue as to why the server is non-responsive?

This is strangely similar to this:

If connected via Wifi, check if "Power Management" is enabled/on with:

iwconfig

Check for RX and TX errors with below one:

ifconfig
